A techy at Boats US told me that if an Optima battery is charged at over 13.8 volts for 90 days it is toast... I do not know where he got his info but he believes it and sells a lot of Optima batteries... he is recommending some sort of voltage reducer from radio shack or the high price spread custom voltage regulators ... his real advice was not to buy an optima unless you are prepared to check the voltage regularly and will dampen down alternator charge rates to 13.8 Does anyone have the skinny on this? |
